On HG, my top Pokemon are Garchomp:83, Arcanine:60, Typhlosion:60, Gyarado:60, and Pidgeot:60. I'm in the middle of training.
Oh, and I finally nicknamed my Arcanine. So here are my nicknames so far:
Typhlosion: Firaga.
Gyarados: Fearsiphon.
Arcanine: Daishar (It stands for 'True Blood' in The Wheel of Time).
